YORK, ASSIGNOR T MANUFACTURING COMPANY, 0F ROCHESTER, NEW YORK, A CORPORATION 0F NEW YORK WINDOW C RANNEL The present invention relates to window channels and particularly to the type designed for use in the window frames of automobiles and other places where it is desirable to maintain a weather tight connection between the sash and the frame as well as to prevent the rattling of the sash in the frame, this application being a continuation in part of an application filed by me on Feb. 16, 1925, Serial To. 9,405, and of my companion application Serial No. 233,162,1'i1ed on the same date herewith. An object of this invention is to provide a construction which is inexpensive to manufacture and which has long life. .An-

other object of the invention is to provide a construction which will make it possible to eliminate the use of rubber, felt and other similar resilient materials which tend to harden quickly. A further object of the invention is to provide a` construction which will make it possible to depend solely on the surface of a textile fabric for obtaining the resiliency necessary to exclude the weather and prevent rattling of the sash so as to obtain longer life in the window channel.

To these and other ends, the invention consists of certain parts and combinations of parts. all of which willI be hereinafter described: the novel features being pointed` out in the appended claims.

Prior to this invention, it has been su gested to employ in window channels yield.- ing or resilient material which will act as a sound preventer and a weather excluder. Materials most generally employed are rubber and felt. Rubber quickly hardens and deteriorates while felt has short life, due to its becoming packed and hardened. In both m instances, the material is expensive. Woven fabric has been used in connection with these materials but merely as a covering means therefor. According to this invention, the relatively heavy woven fabric, as described in my said prior application Serial N o. 9,405 has a relatively soft cushion surface such as a long pile surface which acts as avcushion, preventing the rattling and at the same time excluding bad weather and cold air. The fabric is so supported in those portions forming the side walls of the channel that the pliability or fiexibility of the fabric is destroyed except in the cushion surfaces which becomes the sole cushioning means for the sash. The fabric is preferably woven in strip form in such a manner that it is particularly adapted for window channels. Preferably it has selvaged edges which prevent the unravelling of the material in use, and breaks are provided in the cushion surface permitting the strip to be readily foldedV into channel form.

Various modifications of the form of the textile fabric as well as the stifening. means therefor are contemplated. Herein are shown and described a number of modifications but it is apparent that many more are possible.

In Figs. 1 to 6 inclusive, three embodi- 10 ments of the. textile fabric are shown. In Figs. 1 and 2, a woven textile strip is employed which has selvaged edges l to keep the strip from unravelling, acentral portlon 2 which provides a break between the pile or cushion surfaces 3 arranged on opposite sides of the central portion. In the embodiment shown in Figs. 3 and 4, the selvaged edges 1 are present, and the central portion is a pile or cushion surface 2a with parallel longitudinally extending breaks 2b separating the portions 2a from the cushion or pile portions 3. In the embodiments shown in Figs. 5 and 6, the fabric is the same as shown in Figs. 3 and 4 except that two wide longitudinally extending breaks 4 are provided beyond the cushion or pile surfaces 3.

One manner of using the textile fabric, as illustrated in Figs. 1 and 2, is shown in Fig. 7, the fabric being bent or folded as at 5 at the junctions between the sides of the break 2 and the cushion or pile surfaces 3, being arranged in a channel member 6 formed of rigid or unyielding material, such for instance, as sheet metal, or other suitable material, and being secured by any suitable means4 on the inner faces of the channel which is thenplaced in the frame 7 and receives the sash 8.

In the embodiment shown in Fig. 8, the fabric illustrated in Figs. 3 and 4 is secured in the channel member 6 in the same manner as illustrated in Fig. 7, the fabric being bent at the breaks 2b.

In the embodiment shown in Fig. 9, the fabric illustrated in Fig. 6 is used in connection with a channel member 6, like that employed in Figs. 7 and 8. The fabric, in this instance, not only covers the inner faces of the channel member 6 but the break portions 4 .are extended over the outer faces of the side walls and the outer face of the bottom wall of the channel member 6, an adhesive or other means being employed for securing the fabric to the channel member.

In the embodiment shown in Fig. 10, the fabric illustrated in Figs. 5 and 6 has its breaks 4 folded at 9 to overlap the rear faces of the other portions of the fabric and the breaks 4 are held in this position by stitches 10 which pass through the breaks 2. The structure is` then bent on the lines of the stitches and is inserted in a channel member 6a formed of sheet metal and having overhanging retaining lips 6b which engage the fabric at the folds 9 holding the fabric in the channel member. The channel member is formed from sheet metal and providesan unyielding supporting surface for the textile fabric.

In the embodiment illustrated in Figs. 11 and 12, the form of the textile fabric illustrated in Figs. 5 and 6 is employed. A filler in the form of a strip 11 of lead or other soft substantially incompressible material has the fabric folded about it while said strip is in a flat condition as illustrated in Fig. 11, the break portions 4 of the fabric lying on one side of the strip 11 while the pile portions 2 and 3 lie on the opposite side. Stitches 12 are passed throughthe fabric and the metal, preferably in two'parallel lines arranged at the breaks 2b. This secures the fabric to the fillerwhichybeing ductile, is readily bent to the form shown in Fig'. 12, along longitudinal lines intersecting the breaks 2b.

Figs. 13 and 14 illustrate another manner of using the fabric strip illustrated in Fig. 6. In this construction two thin strips 13 of metal or other substantially incompressible or unyielding material are provided for strengthening the side walls only of the channel. These strips abut the fabric on the sides opposite the sides provided with the pile surfaces 3 and the break portions 4 are folded around the edges of the strip 11 to lie on the opposite side of said strips 13. Stitching 14 is then passed through the breaks 2b and through the breaks 4 on the inner edges of the strips 13. The structure is then folded into channel form as illustrated in Fig. 14 and placed in the channel of the frame in which the sash is mounted.

It will be seen from the foregoing that fibre or fingers project substantially at right angles to the inner faces of a channels side walls which are made of incompressible or unyielding material. These fingers are assembled in dense relationship so that they act as lateral supports for each other and are of such a length that they form a cushion which will hold the sash or window out of contact with the unyielding or incompressible side walls of the channel, thus making it possible to do away with the rubber and felt as a cushioning means. Not only do the fibres or fingers act as cushions but they also serve to produce an antifriction surface to keep the sash or window from binding in the channel.

As shown and described, the supporting or reinforcing means such for example as the channel member 6 or strips 11, are substantially spaced from the window sash or glass 8, leaving the relatively long pile fibers to occupy such spaces between the supporting or reinforcing means and the glass which not only affords substantial resilient cushioning means for the glass and reduces its sliding friction, but has the additional advantage of accommodating a considerable variation in thickness of the sash or glass such as results, for example, from the usual variation in thickness in the run of the glass, as well understood in the art.

What I claim as my invention anddesire to secure by Letters Patent is:
